Abstract (en)
[origin: WO2021245368A1] Apparatus (20) for fitting to the machine end of a tracheostomy tube (10) includes both an HME and a speaking valve (30). The HME includes two exchange elements (28, 29) at opposite ends of a housing (23) extending laterally of a coupling (25) for fitting on the tube. The speaking valve has a cylindrical sleeve (31) extending across the housing midway along its length and in line with the tube. The sleeve is rotatable about its axis and has two openings (36) on opposite sides that can be aligned with the exchange elements of the HME to allow gas to flow from the tube through the exchange elements, bypassing the speaking valve. When the patient wishes to speak, he twists and rotates the speaking valve to block flow to the exchange elements and instead to allow air to be inhaled via the valve.
